Abstract: A battery pack case, including: a battery cell housing part made of metal, the battery cell housing part being configured to accommodate, from one side in a second direction, a battery cell in a state in which a plurality of the battery cells are stacked in a first direction perpendicularly intersecting the second direction and are compressed in the first direction, and the battery cell housing part being configured to support a restoring force of the battery cell; and a flow path forming part made of resin, the flow path forming part being provided integrally with the battery cell housing part, the flow path forming part being disposed at another side, in the second direction, of the battery cell, and the flow path forming part configuring a part of a cooling air flow path part through which battery cell cooling air flows.

Abstract: A manufacturing method of a core of a rotating electrical machine includes: a preparation step of preparing a press device; a fixing step of fixing a steel sheet to a shaft member held by the press device by passing the shaft member through a hole provided in the steel sheet and extending in a stacking direction; and a processing step of performing press-working on the steel sheet by the press device in a state where the steel sheet is fixed to the shaft member.

Abstract: A method of manufacturing a rotational electric machine rotor includes: forming a rotor shaft having a non-circular sectional outer shape; forming a rotor core by stacking a predetermined number of magnetic body thin plates each including a center hole having a non-circular shape corresponding to the non-circular sectional outer shape of the rotor shaft; and forming a protruding part for fixing the rotor core and the rotor shaft to each other by inserting the rotor shaft into the non-circular center hole of the rotor core and squashing the rotor shaft extending out of an axial-direction end face of the rotor core by using a predetermined swaging jig to expand the rotor shaft outward beyond an outer periphery of the non-circular section along the axial-direction end face of the rotor core.

Abstract: A shaft of a rotor includes a cylindrical core member and a resin member. An uneven portion made up of first hole portions is formed on an outer peripheral surface of the core member. The resin member covers the outer peripheral surface of the core member, while being adhesively fixed to the first hole portions. A rotor core is attached to a periphery of the resin member.
